Windows/Mac/Linux: Just not too long ago, Firefox released a version that now includes Chrome-like crash protection, which prevents plug-in failures from crashing your entire browser. That feature has now been updated in Firefox 3.6.6, which changes how long the browser waits before terminating. To accommodate for older computers, the waiting time has been changed from 10 to 45 seconds. Firefox 3.6.6 is a free download for Windows, Mac OS X, and Linux.
